` Appimamned March 14., 190s.

To @ZZ whom, t nte/,y erin/cern,.- Be it known that I, JAMES CARTERMcDon- GALL, a subject of the King of Great Britain, residing at Virden,in the county of Dennis, in the Province oi' Manitoba, Canada, haveinvented certain nev7 and useful Improvements in Grain-ShockingAttachments for Binders;

and I do hereby declare that th'e following is a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to Which it appertains to malre and use the same.

My invention relates to apparatus for automatically shocking the grainreceived in sheaves from a self-hinderthat is to say, collecting thesheaves and piling them upright in separate shocks at regular intervalsalon'g the path or' the grain-hinder.

rllie object of my invention is to produce. a machine that may be formedas an addition or attachment to lthe self-hinding harvester at presentin common use and which is Worked .by the main driving mechanism thereofentirelyautomatically, which shall he of light, cheap, and simpleconstruction, and combined on easyrunning principles to perform itsfunctions in a proper manner.

To these ends my invention consists, generally speaking, in ashock-forming receiver mounted to turn on a horizontal shaft andVnormally supported in a raised horizontal position to receive thesheaves of grain and adapted to he turned about its axis at regularintervals to Ydump the sheaves upon the ground, a retaining or butterkplate adapted to form a closure for the front end .of thereceiver tohold the sheaves against fallingout until the shock is ready to be setup', asheai'- carrier adapted to reciprocate in ,a curved path betweenthe lovverend of the hinderdeclr and a point immediately over saidshockforming receiver and to receive the sheaves one by one as they aredelivered thereto by the discharge-arms of the binder and thence carrythe sheaves successively up andernpty them into the upper side of thereceiver, a set oi' compound levers on Which said sheatcarrier ismounted toK enable it to move in the destined path, mechanism connectingsaid compound levers with' the knetter-shaft of the Sera-l No. 147,757.(No model.)

'binderl to operate the same, mechanism coninecting the shaft of saidreceiver operatively with the knotter-shaft ot' the harvester,periodically-operated trip mechanism connected with said set of compoundlevers which op- .erate the sheaf-carrier and arranged tothrow `sa1dreceiver-operating mechanism 1n and out projecting arm of the frameWhile it is receiving the sheaves, and which device forms an importantthough not an essential element of my invention. w

My invention further consists in the particular combinations andconstructions hereinafter described, and more particularly set forth inthe claims.

I have illustrated my improved grain-shocki ing apparatus in theaccompanying drawings, wherein- Y Y Figure l is a front elevation of aself-hinding harvester having my improved apparatus mounted thereon.Fig. 2 is a rear elevation of the same. Fig. 3 is a side elevation ofthe same. Fig. 4 is a. plan viewv of the same.

Fig. 5 is a transverse central sectional elevation of the same lookingtoward the front. Fig. 6 is a plan view of the operating mechanism forthe shock-forming receiver on an enlarged scale. Figxg is a sideelevation of the same. Fig. 8 is a longitudinal central section toillustratethe trip mechanism for the receiver and taken on the line 8 8of Fig. 6. Fig. 9 is a transverse sectional elevation through the same,taken on the line 9 9 of Fi 0f. 8. Fig. l0 is a plan view of a barconnecting the receiver With its supports.

The same numerals of reference denote like parts in all theiigures or"thedrawings.

In the drawings, vreferring first to the main IOO views, Figs. 1 to 5,inclusive, 10 designates the frame of a self-binding harvester ofanyordinary or preferred type, which has an elevator 11, a binder-table12, 'a main wheel 13,' and a sprocket-gear 14, mounted on the shaftthereof, which last is connected by a chain with the sprocket-pinion 16,loosely turning on'a short counter-shaft 17 and thrown into operativeengagement therewith by any suitable clutch mechanism 18, which need nothere be further described, as it forms no part of my invention. On theopposite or righthand end-of the counter-shaft 17 is mounted abevel-gear 19, which meshes with the bevelpinion 20 on the mainoperating-shaft 21 of the harvester, whose forward end has a crankdisk22 and pin 23, to which is connected the pitman which drives thecutter-blade, while its rear end has fixed thereon a sprocket-wheel 24,driving the elevator-chain 25 and throughA it the otheroperative partsof the binding mechanism1ncluding the secondary shaft 26, carrying Vthesprocket-wheel 27, over which the chain 25 passes, and extending fromrear to front of the binder, beneath the table there- Of, and having onits forward end another sprocket-gear 28, which is connected by asprocket-chain 29 with a large sprocket-wheel 30 on the knotter-shaft31. Immediately beneath the binder-table l2 is located the needle-shaft32, carrying the needle 33, which is operated from the shaft 31 by acrank-pin 34,

projecting eccentrically from one of the spokes of the sprocket-gear 30,and a rock-arm 35 on the needle-shaft, connected with the crankpin 34 bya link 36, so as to oscillate the needle as the knotter -shaft revolves.The chain 29 is carried over a small idle wheel or roller 36fL to enableit to clear the end of the needle-shaft and other operating mechanism.The. binder is shown asV having the customary butter-board 37, whichswings laterally upon the table against the butts of the grain, thedrop-board 38 at the lower end of the bindertable, which retains thesheaves until pushed off, and a set of delivery-arms 39, which are fixedto and revolve with the knotter-'shaft and push the sheaves as fast asthey are bound off the end of the binder-deck; but some of the usualparts of a binder are not shown in the drawings, as these form no partof my invention and are omitted for the sake of clearness. v

Bolted to the main frame 10 of the harvester is the shocker-frame, whichcomprises the two horizontal standards 40 and 41, Whose outer ends aresecured together by a crossrod 42. These rods are also connected atintermediate points by parallel beams 43 and 44, in which is journaledtransversely at or near the center a short horizontal shaft 45, which isthe operating-shaft for the receiver to be hereinafter referred to. Thisshaft is shown in sectional detail in Fig. 8, andithas surrounding thesame for nearly its entire length a sleeve 46, which is fixed thereto bydiametrical pins 47. On the inner or lefthand end of this shaft isloosely mounted a bevel-gear 48, which meshes with a bevel-pinion 49,keyed to the main operating-shaft 21, and is therefore in continuousrotation while the harvester is advancing. Between the wheel 48 andthebeam 43 is mounted acylindrical block 50, which is secured to the shaftby one of thegpins 47, and at one side thereof it has pivotally mountedthereon a trip-pawl 51 upon a pin 52, projecting from the side of theblock. This arrangement is shown more clearly in Fig.v 9, wherein it isseen that the pawl 51 is free to rotate through a certain arc about itspivot. rlhe trip-pawl 51 has an upstanding arm 53, which is adapted tobe engaged by the butt-end of a trip-lever 54, pivoted on an upstandingbearing-bracket 55, fixed to the standard 40 of the shocker-frame, andwhen engaged by this lever the pawl 51 is held, as shown in Fig. 9, Ainupright position. When this lever is caused to be tilted, so as todisengage the arm 53 of the pawl, the latter is overbalanced, so as tofall into the position shown in dotted lines in Fig. 9, wherein the heel56 of the'pawl strikes against the sleeve 46, and the nose 57 is therebytilted up, so as to become engaged with one of three pins 58, which.project from the rear or righthand face of the bevel-gear 48; but whenthe pawl is held upright, as in full lines in Fig. 9, it will be seen'that the pins rotate without engaging it, because the arm 53 of the pawlis offset to the right, so,as to clear these pins. As soon, therefore,as the pawl is disengaged by the trip-lever 54 it becomes engaged withone of the pins of the rotating gear 48, and thereby the shaft is set inmotion and rotated. Y

Mounted transversely in the shocker-frame is a shaft 59, which isarranged forwardly of the center of the binder and at its outer orright-hand end is bent upwardly in the form of a supporting -arm 60. Tothe arm 60, midway thereof, is clamped by straps 61 an auxiliarybracket-arm 62, and the ends of the arms and 6.2 which projecthorizontally beyond their upright portions are connected togetheradjustably by a plate 63, having slots 63a therein, as shown in Fig. 10.On the plate 63 is supported the shock-forming' receiver 64, which ispreferably of roughly conical .or pyramidical form, having both endsopen and held in shape by the angle-iron frames 65 and 66. As shown, thelarger end of the receiver is directed forwardly, and the lower sidethereof slopes downwardly. The upper side is open and has hinged"thereto at 6 7 a closure-door 68,' which is kept normally closed by theforce of a torsion-spring 69, mounted on the pintle of the hinge. Thefree side of the door 68 is provided with a long rearwardly-projectingarm 70, which as the receiver is brought up to its IOO al strongcompression-spring 81.

- 90 on the butter-plate and whose other end is pivotally secured to theforwardly-extendtending arm 72, which projects from the"k plane, and itsother arm is connected by a link raised or horizontal position engageswith the hooked extremity 71 of a horizontally-exframe and is securedthereto, so as to hold the door 68 open during the formation of theshock. The receiver is also preferably of four-sided form, beingdestined to receive eight sheaves at a time and to press them into afour-sided shock, four of the sheaves being pressed into the corners ofthe receiver, whilev the other four occupy intermediate positions. Whenthe shaft 59 is turned forwardly, so as to lower the receiver into theposition shown in dotted lines in Fig. 3, the door automatically closes,because the arm 70 is raised out of engagement with the arm 72.

The receiver-shaft 59 is operatively .connected with the crank-shaft 45hereinbefore described, as follows: The shaft 59 has keyed thereto, asshown in Fig. 7, a rock-arm 7 8, which is in line with a crank 74,secured to the end of the shaft 45. These two are connected by a link 75, which is pivotally connected to the arm 7 3 by a lpivot-pin 76 and tothe crank-pin 77 of the crank 74 by a longi-A tudinal slot 7 8, so thatthe crank-pin has a sliding movement with relation tQ the link 75. Thecrank-pin 77 is shouldered, as shown in Fig.4 6, and secured to itsouter end is a bracket 7 9, having a pin 80, which is surrounded by- Asecond bracket 82 is adjustably secured to an inter,- mediate point ofthe link by means of a bolt 83, which runs in a slot 84 of the bracket,and this bracket has a hole through which the pin reciprocates, and litsupports the end of the spring 81. It will be seen that this arrangementserves to give a resilient connection between the operating-shaft of thebind er and the shook-forming movements of the receiver in order toconform with the unevenness of the ground, so that the receiver will notbe forced against the ground so hard as to cause it to be bent or theapparatus tobef come deranged. y

On the forwardouter end of the shockerframe is bolted an uprightpost 85,whose upper end is reduced to form a pintle 86,\on' which is pivoted thedoor or buttenplate 87 by means of its horizontal angle-iron beams 88.This butter-plate is adapted to close the forward open end of theshock-forming receiver to prevent the sheaves from falling therefrom,and, further, to abut against the ends of the sheaves to cause them toassume an even position. This door is opened and closedV by a link-rod89, which engages a ring ing arm of a bell-crank lever 90, pivoted on ashort upright post 91, secured to the shockerframe. This lever vibratesin a horizontal 92 .to a pivot-pin 93, fixed at an intermediate point inthe rock-arm 7 3. By this arrangethe butter-plate is likewise swung backagainst the endv ofthereceiver. It will be observed, moreover, 4fromFig. Sithat the upright post 85, which carries the butter-plate, issecured by bolts 94 in a slot95 on the cross-piece42 of the frame,whereby said butter-board may.Vv be adjustedl to occupy a plane 4at asuitable l distance from the end of the receiver corresponding to thelength of the grain. which is being cut. s

In order to provide for placing the sheaves successively in the receiveras they are delivered by the dischargearms 39 from the end of f thebinder-deck, I provide a slieaf-carrier 96, which is in the shape .of asemicircular troughv having converging end plates 97, this carrier fbeing of about the proper length for the grainsheaves and the end plates97 causing. the: sheaves to be each laid in its-proper place in` themiddle. The sheaf-carrier 96 is supported on the ends of two swingingarms 98 and 99,

- which are pivoted, respectively, in the projecting ends 100 and 101 ofa Alever-frame 102, consisting of two slotted transverse arms joined bya longitudinal member 103` and pivoted at their inner ends on pintles104.and 105, formed 1 on the ends ofV brackets 106 on upstanding IOOposts 107, secured -to the opposite ends of the shocker-frame. When theframe 102 is resting inits lowest position, which is the normalposition, the pivoted sheaf-carrier 96 rests on the cross-bar 103, and'in this position it faces the end of the binder-table, as illustrated inFigs. 1 and 5, so as to be ready to receivea lslieaf therefrom. When,however, theframe 102 is raised and turned about its pivots, the arm 98,which carries a rectangularlyprojectingfinger 108, extending beyondthe'pivot-point 100 strikes against a horizontally-projectingoverhanging arm 109, secured to the shocker-frame, so as to cause thesheaf-carrier to be rotated about its pivot-points 100 and 101 ,until itreaches the position shown in dotted lines in Fig. 2, in

which the finger 108`abuts against the down f wardly-extending tongue110, .arranged at the proper point of the arm 109, so as to prevent IIOthe tipping movement yfrom proceeding further and the sheaf-carrier fromfalling over. In this position the sheaf carried in the carrier will betumbled out and allowed to drop into the sheaf-receiver through the opendoor Y the lever-frame 102 to oscillate it alternately up and down is asfollows: The knotter-shaft 31 instead of being arranged to overhang thebinder-deck and journaled only-at one end is carriediclear across thelatter, and its rear end is mounted in a bearing 111, formed on theshocker-frame, and on the rear end of the shaft beyond the bearing 111is fixed4 a crank 112, which carries a long crank-pin 113, this beingdisposed in the same axial line with the crank-pin 34, which latter isalso prolonged in a reduced extension 114, and-the two pins 113and 114engage in slots 115 and 116 in the side bars of the frame 102, so thattherotawith their respective slots in the members of the frame 102. Atevery revolution, therefore, of the knotter-shaft the frame 102 will beraised, and consequently the sheaf-carrier will raise the dischargedsheaf and deliver it into the receiver and thereafter will descend toits place again ready for another sheaf as soon as the discharge-armshave completed their revolution..

The connection between the receiver and the sheaf-carrier is such as tocause the former to automatically dump its load and set up the shockafter a predetermined number of sheaves have/been delivered thereto, andthe present machine is adapted to form shocks of eight sheaves each. Tothis end I provide a ratchetwheel117, having eight teethl correspondingto the number of sheaves Whichgo to form a shock, and this wheel ispivoted on a bracket 118, secured to the side of the post 107. With thisWheel coperates a pawl-rod 119, which is pivoted to the front side armof the frame 102, as at 120,- and the free end of this rod drags alongon the teeth of the ratchet-wheel and advances the same by one tooth ateach downward oscillation of the sheaf carrier. This wheel 117 has onits rear face a pin 121 at one point of its periphery, which engageswith a finger 122, formed on the forwardlyprojecting end of the trip-rod54, hereinbefore described in connection with the trip mechanism shownin Fig. 8, the connections as a whole being illustrated most clearly inFigs. 6 and 7. It will be seen, therefore, that at each revolution ofthe wheel 117-that is to say, after eight sheaves have'been successivelydelivered by the carrier to the receiverthe pin 121 will strike thefinger 122 and raise the opposite end of the pawl-rod 54, whereby thepawl 51 is caused to fall and become engaged with one of the pins 58 onthe rear face of the continuous rotating bevel-gear 48, thus rotating itand setting the shock forming mechanism' in motion. After one revolution#saws has been performed by the shaft 45 the pawl 53 will again becomeengaged with the lever v 54, which has meantime been dropped, and willbe thereby pushed out of engagement with the pin 58, and the' receiverwill remain stationary until the ratchet-wheel 117 has completed anotherrevolution, when the same cycle of operations will be repeated.

In order to prevent any possible back motion of the operating mechanismfor the receiver-shaft, the block 50 is provided with an annular flange123, which at one point thereof has a radial jog 124 therein, whichlatter is engaged when the receiver is in its normal position-that is tosay, at the upper end of its stroke-by the pawl 125, pivoted to theshocker-frame by a bolt 126. I-n order further to counterbalance theweight of the moving receiver, I provide a retractile spring 127, oneend of which is hooked over a pin 128, forming the reduced end of thepin 93, and tlie other end is hooked into a bar 129, adjustably securedto the frame by an adjusting-screwV 130 and nut 131, whereby the tensionof the spring 127 may be adjusted to the proper amount to hold thereceiver resiliently in its upright position. When the receiver isempty, it will therefore have a tendency to fly back into this position,and thus aid the power imparted to it by the operating mechanism; butwhen the receiver is full of sheaves and ready to descend the weightthereof will overloalance the spring` 127, and thus in this positionalso it will assist the motion of the operating mechanism.

I preferably further counterbalance and `equalize the motion of theoscillating frame 102 by meansof a pair of springs 132, which are hookedinto rearwardly-extending arms 134 at the sides of the frame and whoseother ends are secured to stationary parts of the shocker-frame, so asto balance the weight of the sheaf-carrier and the overhanging parts ofthe frame 102.

It will be understood that in the descending motion of the receiver itis operated very quickly to set up the shock and return to its placeagain before the harvester has advanced far enough to permit the edge ofthe receiver to strike the top of the shock and tip it over before ithas cleared the latter. In former machines built by me the longitudinalbeams of the shocker-frame which carried the receiver-shaft were madeslidable in a front-torear plane, so as to yield by a certain amount inorder to allow the receiver time to rise to its position before clearingthe shock; but this has been found unnecessary, as by proper design ofthe parts the return movement of the carrier can, as stated, be madequicker than the advance movement'of the harvester as a whole, andtherefore this portion of the device has not been shown in the presentapplication.

While I have shown in the accompanying IOO drawings the preferred formof my invention, it will be understood that I do not limit myself to theprecise form shown, for many of the details may be changed in form orposition without affecting the operativeness or utility of my invention,and I therefore reserve the right to make all such modilications as areincluded within the scope of the following claims or of mechanicalequivalents to the structures set forth. f
